{"version":"1.0","type":"rich","title":"JavaScript事件","description":"This example demonstrates a simple user interface for selecting and previewing sound effects using native JavaScript event handling. The page provides a dropdown menu with four sound options and a \"试听\" (preview) button that triggers playback of a fixed audio file hosted remotely. The code uses the HTML `select` and `button` elements, with an inline `onclick` handler invoking the `playsound()` function. This function accesses the `audio` element by ID and calls its `play()` method, relying on the browser’s built-in HTML5 audio API rather than any external visualization libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d94a90787345459886e7159c253a079c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
